3dTracking Free GPS Tracking
A company called 3dTracking is now offering a free service for GPS tracking. To use the service you will need a few things. A GPS receiver, a device running Windows PocketPC/Mobile 5.0 or a Java/Symbian phone, and an internet connection on that device such as a GPRS connection. Palm OS devices should be supported in February.
Once you have those pieces in place, simply download their software, setup an account, and track away! The system uses Google Maps and Google Earth to power the GPS tracking services.
